While I’ve slowed down so much I may have well just stopped doing YouTube, I too rarely did sponorships. The big thing is that the request for the sponorship and what I had to provide would have increased my work by 2-3x and for that extra effort, hours sometimes, I would get 100-200 bucks due to my small channel size.
I’m lucky to have a full-time job that pays me well so I don’t need to worry about sponsors and can do what I want with my content.
